Question

In a large centrifuge used for training pilots and astronauts, asmall chamber is fixed at the end of a rigid arm that rotates in ahorizontal circle. A trainee riding in the chamber of a centrifugerotating with a constant angular speed of 1.9 rad/s experiences a centripetal acceleration of3.5 times the acceleration due to gravity.In a second training exercise, the centrifuge speeds up from restwith a constant angular acceleration. When the centrifuge reachesan angular speed of 1.9 rad/s, the traineeexperiences a total acceleration equal to 4.4 times the acceleration due to gravity.

Explanation / Answer

Angular speed w ‘= 1.9 rad / s
